Gel version Well M1 The special self-modelling gel insert adapts to the individual anatomy of the cyclist and guarantees maximum comfort. The typical SMP4BIKE design optimally relieves sensitive body regions, as these cannot withstand the pressure of body weight (tailbone, nerves, veins and prostate, etc.), and blood circulation is also optimised. Handmade & ergonomic. The "Well M1 Gel" from SELLE SMP is a versatile saddle. It is designed for road bikes or MTBs, but also for daily commuting or single speed. The soft foam padding with gel gives you extra high comfort on this saddle, handmade in Italy, as it also adapts to the rider's anatomy. Thanks to the SMP4BIKE design, this saddle relieves sensitive parts of the body that are not designed to support the body's weight. The undercarriage is made of stainless steel, the base of nylon with carbon fibre reinforcement. The carbon fibre provides extra cushioning when riding over bumpy roads or rough asphalt.
